As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves from Abel's proof to the higher levels of abstraction developed by Galois through modern-day advances. Derbyshire explains how a simple turn of thought from this plus this equals this to this plus what equals this? gave birth to a whole new way of perceiving the world. With a historian's narrative authority and a beloved teacher's clarity and passion, Derbyshire leads readers on an intellectually satisfying and pleasantly challenging historical and mathematical journey.

    His testing of 25 top female pilots for reactions to isolation, centrifuge, and weightlessness proved him right, and 13 exceptional candidates were identified. Despite countless personal and professional sacrifices, these women joined NASA's clandestine new program -- which, after two intensive years, was suddenly, and mysteriously, canceled. Promised the Moon chronicles the dramatic story of the rise and fall of these pioneering female astronauts, patriots betrayed by men like John Glenn, who opposed women astronauts, and by someone from their own ranks. The first writer to track down the surviving Fellow Lady Astronaut Trainees, Stephanie Nolen vividly brings this fascinating and timely tale to life. Historical photographs are included in this riveting account.

    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    In this collection of landmark mathematical works, editor Stephen Hawking has assembled the greatest feats humans have ever accomplished using just numbers and their brains.

    In your kitchen you denature proteins, crystallize compounds, react enzymes with substrates, and nurture desired microbial life while suppressing harmful bacteria and fungi. And unlike in a laboratory, you can eat your experiments to verify your hypotheses. In Culinary Reactions, author Simon Quellen Field turns measuring cups, stovetop burners, and mixing bowls into graduated cylinders, Bunsen burners, and beakers. How does altering the ratio of flour, sugar, yeast, salt, butter, and water affect how high bread rises? Why is whipped cream made with nitrous oxide rather than the more common carbon dioxide? And why does Hollandaise sauce call for "clarified" butter? This easy-to-follow primer even includes recipes to demonstrate the concepts being discussed, including: Whipped Creamsicle Topping—a foam; Cherry Dream Cheese—a protein gle; Lemonade with Chameleon Eggs—an acid indicator; and more!

    This stirring book reveals how scientific discovery has altered our perception of who we are and where we stand, and challenges us to weigh what we will do with that knowledge. Photos, many in color.

    Nixon had left the White House in disgrace, the nation was reeling from the catastrophe of Vietnam, and in 1979--the year the book appeared--Americans were being held hostage by Iranian militants. Yet it was exactly the anachronistic courage of his subjects that captivated Wolfe. In his foreword, he notes that as late as 1970, almost one in four career Navy pilots died in accidents. "The Right Stuff," he explains, "became a story of why men were willing--willing?--delighted!--to take on such odds in this, an era literary people had long since characterized as the age of the anti-hero." Wolfe's roots in New Journalism were intertwined with the nonfiction novel that Truman Capote had pioneered with In Cold Blood. As Capote did, Wolfe tells his story from a limited omniscient perspective, dropping into the lives of his "characters" as each in turn becomes a major player in the space program. After an opening chapter on the terror of being a test pilot's wife, the story cuts back to the late 1940s, when Americans were first attempting to break the sound barrier. Test pilots, we discover, are people who live fast lives with dangerous machines, not all of them airborne. Chuck Yeager was certainly among the fastest, and his determination to push through Mach 1--a feat that some had predicted would cause the destruction of any aircraft--makes him the book's guiding spirit. Yet soon the focus shifts to the seven initial astronauts. Wolfe traces Alan Shepard's suborbital flight and Gus Grissom's embarrassing panic on the high seas (making the controversial claim that Grissom flooded his Liberty capsule by blowing the escape hatch too soon). The author also produces an admiring portrait of John Glenn's apple-pie heroism and selfless dedication. By the time Wolfe concludes with a return to Yeager and his late-career exploits, the narrative's epic proportions and literary merits are secure. Certainly The Right Stuff is the best, the funniest, and the most vivid book ever written about America's manned space program. --Patrick O'Kelley

    The city had been dumping barely treated sewage into its harbor, coating the seafloor with a layer of "black mayonnaise." Fisheries collapsed, wildlife fled, and locals referred to floating tampon applicators as "beach whistles." But before the plant could start operating, a team of divers had to make a perilous journey to the end of a 10-mile tunnel-devoid of light and air-to complete the construction. Five went in; two never came out. Drawing on hundreds of interviews and thousands of documents, award-winning reporter Neil Swidey re-creates the tragedy and its aftermath in an action-packed narrative. The climax comes when the hard-partying DJ Gillis and his friend Billy Juse trade jobs at a pivotal moment in the mission, sentencing one diver to death and the other to a trauma-induced heroin addiction that eventually lands him in prison. Trapped Under the Sea reminds us that behind every bridge, highway, dam, and tunnel-behind the infrastructure that makes modern life possible-lies unsung bravery and extraordinary sacrifice.

    It is a story of pioneering technology, of the American entrepreneurial spirit, and of the tragic collision between the corporation and the lone inventor. Published in conjunction with the PBS documentary. 8 pages of photographs.

    Probably no one felt more disappointment and regret than Allan McDonald, who had warned us not to launch that day. His story tells of loss, grief, and the eventual rebuilding and recovery."--Robert "Hoot" Gibson, former Space Shuttle pilot and commander   "A major contribution to a difficult episode in the history of human spaceflight."--Roger D. Launius, Division of Space History, Smithsonian Institution   “McDonald tells the heartbreaking tale of how he saw his words of warning ignored, and the fateful consequences of that decision.”--Donald C. Elder III, Eastern New Mexico University   On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals, including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation’s collective memory.   In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.  As he fought to draw attention to the real reasons behind the disaster, he was the only one targeted for retribution by both NASA and his employer, Morton Thiokol, Inc., makers of the shuttle’s solid rocket boosters. In this whistle-blowing yet rigorous and fair-minded book, McDonald, with the assistance of internationally distinguished aerospace historian James R. Hansen, addresses all of the factors that led to the accident, some of which were never included in NASA’s Failure Team report submitted to the Presidential Commission.  Truth, Lies, and O-Rings is the first look at the Challenger tragedy and its aftermath from someone who was on the inside, recognized the potential disaster, and tried to prevent it. It also addresses the early warnings of very severe debris issues from the first two post-Challenger flights, which ultimately resulted in the loss of Columbia some fifteen years later.
